' WELL-BAILING -OPERATING MECHANISM.

- "B'eitl'cnown'that I, DAVID Bnowu WHITE- HiLL, a-citizen of the United States, residing at'North'Clarendon, in the county of War- "ren and State of Pennsylvania, have invented a new and usefulW'elhBailing-Operspecification.

One of the principal objects is to provide acomparatively simple and novel structure that is entirely effective for elevating and lowering the bails, or, in fact, any other articles or devices, said structure bein particularly adapted to operate such bai s and be controlled at a distance,.thereby permitting the machine to be used in bailing out wells that are scattered over' a comparatively large area.

In the embodiment illustrated a suitable frame is employed, which in the present structure comprisesa base 8, having standards 9. At one end of the frame is located a driving-shaft 10, which is continuously operated from any suitable source of power and '45 has secured thereto a driving wheel 11. The

"hub 12 of this driving-wheel projects beyond;

the shaft 10, forming a socket 13. A hollow drum-shaft 14 is journaled in the frame and is disposed in line with the driving shaft 10.

The bearings for the shaft 14 consist of spaced 1 ta in rollers 16. The boXings 15 are verti- Specification of Letters Patent. 1 Amman filed May 24,1906. Serial No. 318,500.

in offset ears on the upper ends of the 1 standards, have threaded engagements with ears 21, carried by. the boxings, said screws thus serving to raise or lower the'bearings.

The shaft 14 carries between the bearings a pair of drum-heads 22, having hubs 23, that are fixed to the shaft by setscrews 24 or by any other suitable means. The outer ends of these hubs are beveled, as shown at 25, and

said outer ends engage the inner portions of. the inner ends of the rollers, as be evident by reference to Fig. 3. A thrust-bearing member 26 is secured to one end of the shaft and has a hub 27, providedwith a'beveled inner end-28, that engages the inner portions of the outer ends 'of the adjacent rollers, as shown in Fig. 3. Abrake-wheel 29 is secured to the opposite end of the shaft and has a hub. 30, provided with a beveled end 31 that en'ga es the outer ends of the rollers bearing. The above-described structureand relation of parts are im ortant'. It has been found that with the rol er-bearings as ordinarily constructed the rollers have a tendency to take positions in angular, relation to the shaft instead of parallel there- By having the beveled ends of the varito. ous hubs, however, engaging the inner portions of the roller'end this tendency is over come, and ex erience has demonstrated that the rollers wil remain parallel to the shaft. In this connection it is to be noted that parts of the hoisting mechanism constitute the means for thus retaining the rollers.

Clutch mechanism is mounted on the outer face of the brake wheel 29. In the present embodiment carrier-blocks 32 are adjustably mounted on said outer face and are movable toward and from the axis of rotation of the wheel. These blocks are held in adjusted position by bolts 33, passing through slots 34 therein and into the wheel. Guide-lugs35, carried by the inner sides of the blocks, en-

..gage i'n slots 36 in the wheel, and an'adjust 'outer ends of the plates are and to the wheel,

- inner sid'es'of the jaws, their inner ends havmg heads l6, that are in vable toward and serve to urge 'the jaws inwardly away from the driving-wheel 11;

Thrust-bars 44 are shdablymounted1n keepers 45, secured to the brake-wheel 29.

The outerends of the thrust-bars engage the away from each other. An actuating-stem 47 is longitudinally slidable 1n the hollow drum-shaft 14. One end of this shaft carriesa tapered-head 48, that is movable between the heads 46 of the thrust-bars, so as to separate said bars, and thereby swing the jaws 38 outwardlyagainst the tension of the spring" 43. A guidepin 49 is preferably mounted in the head 48 and is removable therefrom, said pin extending between the 5 heads 46 and having a retaininghead 50.

This pin, together with the head 48, operates. back and forth in the socket 13, formed in.

the hub of the driving-wheel. The opposite end of the stem 47 is )rov ded with an annular groove 51, n1 whlc 11s engaged a yoke 52.

i This yoke is pivotally mounted on a lever 53,

lulcrumed at its lower-end upon thebascB and having its upper end disposed adjacent to a post 54.

It will be evident that when the lever 53 is swung in one direction the stem 47 will be'moved longitudinally within the drum, the head 48 will spread the thrustbars- 44'apart, and the jaws will engage the driving-wheel, thus clutching the drum to the driving means. In order to prevent the longitudinal movement of the drum with the I s.tem, it will be observed that the heads 46 of the thrust-bars 44 are abutted against the hub 12 of the driving-wheel 11, as shown in Fig. 3, and, furthermore, this end thrust or movement is prevented by a bracket or 'kee or 55, see-ured to one of the standards 9 an embracing a flange 56 on the thrust member 26. It is also to be observed that by adjusting the carrier-blocks 32 toward and from each other the outer ends of the thrust-bars 44 may be made to engage the jaws 38 at di'tl'erent distances from their ends, '4

thereby varying the force exerted on said aws.

.lever 62, fulcrume'd on the frame, has a link connection 63 with the shank 61. This. lever 62 extends transversely of the lever 53 and has its free end disposed adjacent to the post 54. A cable 64, connected to the free end ofthe lever 62, also has a connection, as 1 shown at 63, with the upper end of the post 54, and a pulley 65, carried by the upper end cl the lever 53, operates on the cable 64-, An actuating-cable 66, passing around a guidesheave 67, also passes around a pulley 68 on the lever One end, as 69, of the cable 66, is secured to the supporting-frame. V The other end of said cable is located at the well which is being bailed, and consequently the said cable 66 can be extended in any direc* tion desired. The bail-operating cable is shown at 70 and is of course wound upon the drum formed by the shaft 14 and the two heads 22. p

The operation of the structure may be briefly described as follows: The driving shaft and wheel are continuously rotated by any suitable means, as already described. As long as the head 48 of the actuating-stem 47 is withdrawn from the thrust-rods 44 the jaws 38 are out of contactwith the drivingvrheel, andconsequently the hoisting mechanism is not operated. If the cable 66 is loose, the lever 62, which is provided with asuitable weight, as 62, is in its lowermost position. Consequently the band 57 will bind upon the wheel 29 and hold the drum against rotation. If it is now desired to Wind the cable upon the drum, the operator has only to draw upon the cable-66, whereupon the lever 53 will be moved to carry the head of the stem '47 between the thrust-rods, thus swinging the jaws into engagement with the dr1vmgWheel. 'A swinging movement of the lever 53 carries the pulley 65 away from the post 54, and as a result the lever 62 will be elevated, thereby loosening the brakeeband. When it is desired to stop the drum and hold it, it is only necessary to release the cable 66,

Whereupon,.as already described, the jaws will be disengaged from the driving-wheel and'the brake-band applied to the driving- Wh'eel. On the other hand, if it is desired to lower the ball into the Well then the cable 66 is held so that the 'lever 53 is in an intermediate position, iii which case the jaws 38 will be out of engagement with the driving-Wheel and the brake-band 57 Will be sufiiciently loose to permitthe drum to turn freely.

' From the foregoingit is thought that the I construction, operation, and many advantages ot' the herein-described invention Will be apparent to those skilled in the art with- Out further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may he resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
